Begin by separating the chicken wings into two parts: the drumsticks and flats. Rinse them under cold water, pat dry with paper towels, and place in a large bowl. Season generously with kosher salt and freshly ground black pepper.

Set your grill to medium-high heat, aiming for about 400°F (200°C). Close the lid and allow it to reach this temperature.

Once the grill is hot, place the seasoned wings on the grates and grill for 10-12 minutes, flipping every 3 minutes.

When the wings are perfectly grilled, remove them from the heat and transfer to a large bowl. Add pesto sauce, tossing until well-coated.

Arrange the coated wings on a serving platter. Optionally, sprinkle red pepper flakes or garnish with fresh basil.
